UNITED STATES HUGH VVIGI-ITMAN, OF PITTSBURG, PENNSYLVANIA.

IMPROVEMENT IN MACHINES FOR CARDING FIBROUS SUBSTANCES.

b'pecifeation forming part of Letters Patent No. 3,904, dated February12, 1845.

To all whom it may concern:

Be it known that I, HUGH WIGHTMAN, of Pittsburg, Allegheny county,Pennsylvania, have invented a new and useful Improvement in theConstruction of Carding-Mashines, of which the following: is a full,clear, and exact description.

My invention consists in dispensing entirely with the main cylinder ofthe common oarding-machine and disposing the lioker-in and the strippersand Workers around the lower part of the periphery of the doffer, so asto act doubly, both receiving and delivering the material to he cardeddirectly from and to the doifer without the aid of the main Cylinder.

To explain my improvement and enalole the public to understand it fully,I refer to the drawing hereto attached, with the references.

The main cylinder is dispensed with, and

' the strippers and workers y are arranged around the lower part of theperiphery of the doffer and so disposed as to operate as a suhstitutefor the main cylinder andV to deliver to and receive from the doffer,and worked by an endless strap.

l 2 3 are the lap-roller, counter-wheel, and feed-rollers, asin theusual machines.

4 is the licker-in, and receives from the feeding-rollers and deliversto the doffer, and has a motion contrary to what is usual.

5 is the doffer.

6; 7, 8, and 9 operate as the workers and strippers of the commoncarding-rnaohines, but so moving as to receive from and deliver to thedoffer.

The licker-in and the workers and strippers are thus applied immediatelyto the lower circumference of the dolfer, delivering to and receivingfrom the doifer itself.

ct is the pulley of 4, Z9 of 5, c of 6, d of 7, e of 8, andfof 9.

10 is a crank on the end of the shaft of 8, and moving a sword or pitman11, which works the comb l2, the material carded to he conveyedv fromthe doffer, as is usual.

@c 0c are the puppet-head stands, sustaining the shafts of the workersand strippers.

The licker-in and Workers and strippers are to loe run hy a winding orendless strap moved by drum 14, driven by pulley 15, or hy other usualmode, so as to receive and deliver froin and to the doffer, as pointedout by the arrows on each cylinder.

NV hat I claim as my invention is- The dispensing with the main cylinderof the common cardinginachine hyso disposing of the lieker-in andWorkers and strippers aroupd the lower part of the circumference of thedoffer and giving them such mot-ion as to deliver to and receive fromthe doifer itself wit-hout the aid of the main cylinder.
